High impact year expected.

Of note is that CSU's landfall probabilities are based on the total number of storms predicted so an inactive season would have a lower landfall probability and an active season would naturally have a higher landfall probability. However, they do not take into consideration the anomalous strength of the ridging which also increases or decreases the landfall probabilities. In my opinion, an inactive year with stronger than normal rigding may actually have a higher la...

Atlantic Hurricane outbreak

By: SLU, 1:20 AM GMT on September 15, 2010

After the "slow" start, we've now had eight named storms, four hurricanes and three category 4 hurricanes in the last 24 days now putting us ahead of every single hurricane season in the Atlantic Basin since 1936 except for 1995 and 2005. We are even ahead on this date of even the lengendary 1969, 2004 and 2008 seasons and only 4 named storms behind 2005! The poor black birds are going to be extinct by the end of the year.
